Best Self Hosted Alternatives to Better Auth

Melody Auth is a turnkey OAuth 2.0 and authentication system you can run on Cloudflare Workers (with D1 and KV) or self-host on Node.js with Redis and PostgreSQL. It provides a complete auth server, management UI, and developer-facing APIs and SDKs for integrating secure login flows into applications.

Key Features

• OAuth 2.0 flows including authorization, token exchange, refresh token revoke, scopes, consent, and user info retrieval
• OpenID Connect support (discovery/openid configuration) and JWT/JWKS-based authentication with key rotation
• Multi-factor authentication options including email/OTP/SMS, passkeys, recovery codes, and “remember device”
• External identity providers including social login (Google, GitHub, Discord, Apple, etc.) and OIDC providers; SAML SSO in Node.js deployments
• Role-based access control (RBAC), user attributes, account linking, organizations and groups
• Admin panel for managing users, apps, roles/scopes, organizations, IdPs, and logs (including impersonation)
• Server-to-server REST API plus embedded auth API and frontend SDKs for web, React, Angular, and Vue
• Brute-force protection and security-focused logging for sign-in and verification flows

Use Cases

• Ship OAuth/OIDC authentication for new products with a built-in admin console
• Add MFA, passkeys, and social login to existing apps without building auth from scratch
• Run an internal identity provider for multiple apps with RBAC, org/group management, and audit-friendly logs

Melody Auth is well-suited for teams that want a complete, customizable auth stack with minimal operational overhead on the edge or full control in a traditional server deployment.
